[Gate-users] failed to load external entity "Materials.xml"

[Anne Sauve]

Hello,

I have typed the mandatory line:
/gate/geometry/setMaterialDatabase GateMaterials.db

and it's much better
but I am getting a warning when I insert a box.

Idle> /gate/world/daughters/name SPECThead
Idle> /gate/world/daughters/insert box
I/O warning : failed to load external entity "Materials.xml"
 GateDetectorConstruction::insertARFSD  entered 
 created a ARF Sensivitive Detector 
 created command /gate/systems/SPECThead/arf/setARFStage

Could you help me with that it seems correlated with materials

Thank you very much
